ChatGPT vs. Bing Chat: which is the best AI chatbot?

Bing Chat and ChatGPT are two of the latest natural language chatbots to become widely available, and both are competing for your attention and text prompts. Both AIs are based on similar language models, but there are some distinct differences between them, making the ChatGPT versus Bing Chat debate one well worth having.

If you want to play around with these two exciting tools, here’s everything you need to know to pick the right one for you.

How do you use ChatGPT and Bing Chat?

Both Bing Chat and ChatGPT are available for general use, but the way you access them is a little different.

ChatGPT is widely available and accessible through the main OpenAI website. You can use ChatGPT for free once you’ve made an account, and there are ways you can quickly access it from your desktop or Mac if needed.

Bing Chat is also available and is no longer on a waitlist. However, it does require you to download the latest version of Microsoft Edge, which is kind of annoying. On the other hand, Bing Chat is available on more platforms, including the mobile Edge browser for smartphones. Not only can you access it through the official website, but you can access it through Bing on any supporting device too. There are also integrations of Bing Chat in Skype, Teams, and the Edge browser. ChatGPT is available in Slack and is soon coming to Discord.

ChatGPT is free to use, but there is a premium paid tier, known as ChatGPT Plus, which gives greater access to the tool, including GPT-4. Bing Chat is entirely free, but there’s a limit of 150 conversations you can have per day, with a limit of 15 chats per session. Conversation length is also limited to 2,000 characters per prompt or response. ChatGPT has a character limit as well but doesn’t currently have a limit on conversations you can have per day.

What language models do ChatGPT and Bing Chat use?

The current version of ChatGPT that you can access for free is based on the GPT-3.5 language model. According to Microsoft, Bing Chat actually uses the more advanced GPT-4 model, which was recently announced.

In theory, that means Bing Chat should be more useful. Just be careful you don’t wander into Wargames territory by playing certain games, as Bing Chat has been known to get a little existential at times.

Both ChatGPT and Bing Chat are based on the same fundamental language model, known as GPT-3.5. They have access to information up to and including 2021, which gives them huge scope for responding to natural language questions, and with relatively up-to-date information. However, that can leave holes in their knowledge.

Bing Chat, on the other hand, has the ability to pull from more recent web sources. It has also undergone additional training to make it more capable of following instructions and completing more nuanced tasks.

What can you do with ChatGPT and Bing Chat?

The core function of both ChatGPT and Bing Chat is that they can understand when you ask them questions or make statements in natural, human language. Both services support a range of languages, though ChatGPT is more focused on English, whereas Bing Chat offers a wider array of non-English languages.

Both Bing Chat and ChatGPT can be used for research, asking questions that go beyond what traditional search engines are capable of understanding. For example, I used it for a recent article I wrote about Nvidia’s biggest failings, by asking, “What are the reasons for Nvidia’s largest stock value drops?” If it’s something you’d type in Google Search, you can also put it in one of these AI chatbots.

ChatGPT is particularly good at creative writing, so asking it to write something about a certain topic, or in the style of another writer, will result in a very credible attempt at completing what you ask of it. Do note, though, that ChatGPT cannot fact-check itself against multiple sources, so it can introduce errors with just as much confidence as it does statements of fact.

Bing Chat isn’t quite so good at that type of writing, as it can’t provide such lengthy responses and is more driven by facts than creative endeavors. However, Bing Chat has a number of discrete modes that it can be switched into, turning it into a virtual assistant or a casual friend who will chat with you about everyday life.

Being able to choose between Creative, Balanced, and Precise is fantastic, allowing you to tailor your conversations more aimed at your goal. The one-size-fits-all approach of ChatGPT requires a bit more nuance and description in the prompts.

There’s also a hidden game mode, where you can play trivia, hangman, and other simple games with it.

Lastly, Bing Chat has its new Copilot mode, which splits it into three modes: chat, compose, and insights. Open as a sidebar along what you’re other browsing, these modes help Bing Chat narrow down responses and focus your prompts.

AI image generation

Bing Chat has recently gained the feature to generate AI imagery, which Microsoft calls Bing Image Creator. Built on an “advanced” DALL-E model, Bing Image Creator allows you to generate images right in the context of a chat — something ChatGPT hasn’t yet done.

OpenAI is the creator of the DALL-E model, of course, but still treats image generation and text generation as two separate products. From what we’ve seen so far, Microsoft is the first company to try and integrate the two together.

Is Bing Chat more accurate than ChatGPT?

Bing Chat has the potential to be more accurate than ChatGPT because it pulls from more recent information and relies on multiple sources of information.

ChatGPT is based on a singular source of data from its language model, so it doesn’t have access to more recent information and cannot cross-reference its responses to confirm accuracy.

Because Bing Chat is based on GPT-4, in theory, it should quite a bit more powerful and nuanced than ChatGPT. The early tests of GPT-4 in ChatGPT Plus have shown some promising results so far, such as one user’s success at creating a workable game of Pong in less than 60 seconds.

In terms of accuracy, the other interesting feature offered by Bing Chat is its “learn more” suggestions. Not only is this a more ethical and transparent way of displaying info, it also gives you somewhere to go next — more like a proper search engine.

Both chatbots have their place

Bing Chat and ChatGPT are new and very exciting tools with heaps of potential. They’re each better at certain things, with Bing Chat better at finding up-to-date information and acting as an assistant, while ChatGPT is more adept at creative conversations or helping with writing in a specific style. It can be great for prompts, or for proofreading something you’ve written.

Bing Chat is a nice place to start though. If it’s your first time, it can be a good place to start, given the guidance and prompting offered by Microsoft. When it comes down to it, though, the limit of 15 chats per session and 150 conversations and the requirement to download Edge will lead people to ChatGPT first, allowing for more exploration without needing to worry about using up your daily allowance.

Apple finally has a way to defeat ChatGPT
A MacBook and iPhone in shadow on a surface.

OpenAI needs to watch out because Apple may finally be jumping on the AI bandwagon, and the news doesn't bode well for ChatGPT. Apple is reportedly working on a large language model (LLM) referred to as ReALM, which stands for Reference Resolution As Language Modeling. Made to give Siri a boost and help it understand context, the model comes in four variants, and Apple claims that even its smallest model performs on a similar level to OpenAI's ChatGPT.

This tantalizing bit of information comes from an Apple research paper, first shared by Windows Central, and it appears to be an early peek into what Apple has been cooking for a while now. ReALM is Apple's own LLM that was reportedly made to enhance Siri's capabilities; these improvements include a greater ability to understand context in a conversation.
